How do I convert BMP to ICO?

Upload your BMP file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting BMP to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

BMP lagrar pixlar helt utan komprimering. Filerna blir stora, men mycket gammal eller enkel programvara som inte kan läsa moderna format kan oftast läsa en BMP.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Is the BMP to ICO converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

Why convert BMP to ICO?

One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.
Webbläsare visar ICO-filen som webbplatsens flik- och bokmärkesikon när du sparar den som favicon.ico.

What to expect when converting BMP to ICO

Ikoner är kvadratiska, så en bild som inte är kvadratisk centreras på en genomskinlig kvadrat. Storlekar som är större än din bild skapas inte, så börja med minst 256 × 256 pixlar.
Din ursprungliga BMP-fil ändras inte: du laddar ner en ny kopia i ICO.
